MACHINE FOR FORMING RECEP'IACLES. N

Application filed November 8, 1911.

To all whom it may concern.

Be it known that I, OHnsLEY T. SMALL, a citizen of the United States, residing at t. Louis, Missouri, have invented. a certain new and useful Machine for Forming Receptacles, of which the following is such a description as will enaccompanying drawings, forming'part of this specification.

Iy invention relates to a machine for performing various operations upon cans or other packages or receptacles, and its object l5 is to provide a machine which will perform t e various operations rapidly and accurately and which, owing to the adjustability of its parts and interchangeability, of its tools;.and holders, will be adaptable to a Wide range ofv'ork on various forms and sizes of receptacles.

In the present invention I have illustrated V a f rovided with accessories for forming upon ordinary cylindrical can bodies flanges either internal or external, and for securing to said can bodies means of a double seam. As above stated, my machine is applicableto a wide range of work,and I do not wish to be understood as limiting myself'to the particular constructions and functionsdescribed except as specifically stated in the claims. In the accompanying drawings, Figure 1 is afront .elevation; Fig. 2 is a rear elevation,.al1 of the cams carried on shaft 125 being omitted, except eccentric 12 1 for rotating'the table; Fig. 3 is a side view, the same parts being omitted as in Fig. 2, the feed chain fordriving the flexible fingers also being omitted, Fig. 4 a vertical central section through the main portion of the machine; Fig. 5 a horizontal section, the standards 51 and 52 being. shown somewhat closer together than in Fig. 4 of the drawings, for the purpose of convenience; Fig. 6 a sectional view of one of. the chucks;' Fig. 7 an enlarged sectional view through the main shaft of the machine; Figs..8, 9 and 10 detail views of the can holders; Fig. 11 an enlarged view of the operating mechanism for the main shaft; 'Fig. 12 a deta l ofthefeeding pawl; Fig. 13 a. side elevation of some of theparts shown in Fig. 11; Fig. 14 a view partly in section and partly Specification of Letters Patent.

50 represents the bed plate of the machine. Secured to this plate 50 is an upright or standard 51 having secured to one side there of a similar but shorter standard 52, as best shown in Figs. 4 and 5. Carried by the standard 52 is the lower part 53 0f the main frame. This frame 53 is secured to a standard by means of a threaded rod 54 passing through a lug 55 and provided with a hand .wheel 56 as best shown in Fig. 14. It will be evident that by rotating the hand wheel 56 the lower main frame 53 of the machine.

may be raised and lowered for In order to theframe 53in any desired position the lug 55 has threaded into it a rod 57, provided with a hand wheel 58 so as to clamp a friction plate- 59 against the upright 52. Th

the purposes-.5 i

e upper main frame 60 of the machine :is

attached to the upright 51 by means of mechanism similar to thatpist described.

01 rep osents the hand wheel for raising a nd lower in: the frame 60, and 62 the hand a wheel for clamping said frame in its adposition. order to support the outer end of the frame ll provide said frame with a bracket 63 in which is threaded a rod 111 supported n from the base 50. This rod 111 is driven sir n ously with the rod 54 by a sprocket chain surrounding sprocket wheels in the two shafts, as best shown in Figs. 1 and 52;. The rod ll'l'inay also be extended upwardly :mdad iustably secured to the upper frame l by means of a bracket 115, and set screw 11% so as to term a tie-bar between the two frames, thus increasing the rigidity of the machine. 1 01 represents a conveyor for delivering the can bodies to the machine. This conveyor 64; deposits the can bodies upon a rotary table 65 carried upon a vertical'shaft 66 jcurnaled in the frame 53. This shaft 66 provided with a. bevel gear wheel 6'7 meshing with a second bevel 'gear wheel 68 carried upon a horizontal shaft 69 also journaled in the frame 53. This shaft 69 is driven by gearing which will hereinafter be described. The rotary table delivers the to a stationary table 70 which surrounds the main spindle 71 of the machine. Di rectly above this stationary table 70 is a disk 72 c: rried upon a sleeve 73 surrounding the spindle 71. This dish 72 carries a removable extension 7 1 shown in detail in Fig. 25. This extension 7 1 is formed in two parts and is held in position by means of tapered pins 753. Formed in the periphery of the exten- 49 s on 74 are a. number of semi'cylindrical rec'e. vs 76 adapted to receive the cans fed onto the stationary table 70 by the rotary table 053. in order to insure the seating of the cans in the recesses 76 1 provide a ram mech- 5 anism shown in Fig. 5 and in detail in Figs. 18 and 19. Secured to the frame 53 is an extension 7'! provided with slots 78 through which passes a screw 79 for adj ustably holdinp; an angle plate 80. This angle plate is 50 provided with a slot 81 through which passes a sc \[V 82 for adjustably holding the frame 8?) of the ram mechanism. Mounted in this frai'nc are a nun'rberof reciprocating rams Sleach provided on its end with 'an anti- 5 friction roller adapted to make contact with. the cans as they pass from the rotary to the non-rotary table and to insure their scaling in the recesses 76. The rams 8 1 are mounted upon l'iorizaontal rollers 86 and 87,

6 and have placed be ween them vertical rolls 88 so as to reduce the rriction to aminimum. The rolls 88 are mounted on trunnions 88, which are staggered as shownin Fig. 5. so that each roll bears only on one ram. The rams are also held down against the rolls 86 and 87 by rolls 89 and are thus free to move with the smallest possible amount of friction. In order to force the rams inwardly soas to seat the cans each of the said rams has secured to it a chain 90 placed in a groove 91 in the rollli? and having secured to. its end a weight 92. This weight 92 is provided at its lower extremity with a threaded opening 93 so that if desired a separate weight 94: may be secured to it in order to vary the tension on the ram 84.

It will be evident that, by this construction, the rams as a whole may be adjusted vertically and also toward and away from the member 74: in. which are formed the re= so -cesses 76. It is desirable also to individually adjust the rams 8 1 to secure their most successful operation upon cans of varying diameter. In order to obtain this result I secure to the upper and rear part of each of the said rams 84; a stop plate 95 by means of a bolt 96 passing through a slot 97 in the said plate. Each of these stop plates 95 is adapted to bear against a cross-bar 98 and thus limit the movement of the individual rains toward the member 7 1. Each of these stop plates is provided with a. lateral projection 99 adapted to strike against a shoulder 100 upon the next stop plate to the right,

so that after any ram has been moved 95 through a predetermined distanceit will actuate the necessary ram to the right thereof.

In order to guide the cans from the rotary table 85 to the point where they are engaged by the rams 84,1 provide a guide plate-mech- 100 anism shown in Fig. 5, and in detail .in Fig. 35. This guide plate mechanism consists of a block 101 pivoted to an arm 102- adjustably secured to the frame 53'by means of a bolt 103 passing through a slot 104'. 105

Sliding on the face of the block 101 is the plate 105 which guides the cans, as it is necessary for this plate to have a slidingv movement as well as pivotal movement.

Secured to the rear of the plate 105 by means of a thumb-screw 10G passing through a slot 107, is a plate 108. This plate 108 slides in a groove 109 in the rear face of the block 101. The plate 108 is pivoted to a ram 110 which is similar to the rams 8-1 hereinbefore described except that it is of course not provided with the anti-friction roll 85 and that its stop plate 95 is not provided with the lateral projection 99 for engaging the next ram to the right. 0

It will be evident from this construction that the plate 105 is. free to move so as to allow the cans to seat properly in the recesses 76, and at the same time it can be adjusted to suit the requirements of cans of varying diameters. The disk 72 hereinbefore described is keyed to a shaft 71 so as to rotate therewith but to be capable of movement in the direction of the length of the shaft. The sleeve 73 carrying th s disk bears upon a sleeve 115 which is loosely mounted upon the shaft '11.

he sleeve 115 is engaged by a lever 116 pivoted at 117'to the frame 53 and her 74 to cans'of varying 71 is proylded directly below the end of theat its opposite end provided wheel 121 of which the said shaft is rotated.

It will be evident that asthe shaft .125 rotates, the ratchet wheel 121, and consequently the member 74- for advancing the cans, will be fed forward step by step. The ratchet wheel 121 will of course be provided with a nimber of teeth 2 may be thrown out of engagement ratchet wheel when it is desired W backward, this pawl is 'with the ratchet wheel 128 which is pivoted to a bracket 129. I This bracket 129 is in' turn means of a pivot The bracket 129 also carries a second lever 131, the position of which is adjusted by means of a'set screw 132. The lever 129 is provided with a rod 133 passing through an opening 134 111 the lever 131. and is surrounded by a; ooilyspring 135.

ltjwili be evident that by compressing the coil spring thelever 128 can be moved. out of engagement with the rear of the pawl 122. Both levers together with bracket 129 can, then to move said wl y means a lever be swung upwardly on the pivot bolt ldOso as to leave the pawl 122 free to gagement with the wheel 121.

This brake also tends to prevent the overrotation. ofthc wheel 121. As such overrotation. of the wheel, however, is likely to the machine, I prefer to.

cause breakage of the brake 138, a positive use in additionto stop mechanism.- v upper face of the wheel 121 Wrtha series of pins 139 corresponding with the number of Th se pins "thewheel 121, the lever 141 will A pawl 7 .provided with and. easy movement 7, so that disengaged from the cans I therefore supply theto :to the member 72, which is provided with a portion 74 like the l 139 are adapted to be engaged by a stop 140 adjustably secured to a lever 14-1 by means of :1. bolt 142. This lever 141 is pivoted to the frame 53 at 143 and is provided at its outer end with an inclined portion 144 adapted to be engaged by a projection 145 on the pawl 122. When the pawl in its forward position therefore, ready to move be lifted so as to move the stop 140 out of the path of the pins. After a short travel however, the lever 141 will drop back so as to bring the stop into the path of the next succeeding in and consequently there will be a positive stop for preventing the over-rotation of the wheel 121. Carried on the shaft 71 above the disk '72 is a head or turret 14G adapted to rotate with said shaft 71 Mounted in this turret 146 are a. number of reciprocating plunger-s 147. These plunger-s are equal in number to the. notches 76 in the member 74, and are adapted to register therewith in radial position. Each ofthe plungers 147 has removubly secured to its lower end by means of a tapered pin 148 a holder 149 which is adapted to embrace the can. cled at 150 so as to enable the holder to readily slip over the can. By removing the pins 148 the holder 149 may be changed to accommodate difi'ercnt" styles or, sizes of calls or to perfoi 'm diiierent operations thereon. In 1* 1g. 1 I have shown holders slots 158 to receive a partition plate, while in Figs. 8. 9 and 10 I have shown the holders as provided with a recess 159 through which a forming roll may project to operate on the can, as will be herein after described. The upper end of each of the plunger-s 147 is provided with a laterally projecting roll 151 which travels between epair of cum tracks 152 end 153, respectively, carried by plates 154 and 155 which are connected by means of bolts lfiiiand secured to the upper frame 60, as shown in Fig. 4-. The plunger-s ll? are slightly tapered as shown in Fig". 7, which. together with their suspension from the roll 151 al lows the holder 149 to. have a pendulur movement which facilitates the-seating of the holder over the cans. The tracks 152 and 153 are secured to the plates 154. and 155' by means of bolts 157, as best shown in Fig.

the said tracks may be easily ren'ioved'to change the elassof work done upon the machine. It will be understood that as the turret or head 146 rotates the plungers 147 will be moved up and down to cause the holders 149 to engage with and be moved upon the table by the member 72.

In case of very tall cans it is desirable have a second moving member lfitl'similar nemovable projecting pleted can body.

. ably connected by a bolt 166 to a bracl ,--167 secured to the frame 53 as best shown projecting portion 74 hereinbefore described. Ordinarily, however, this member may be dispensed with, as shown in Fig. .4. In order to reduce friction, the weight of the turret 146 is supported by a ballbearing 161 carried by the plate 155, as shown in Fig. 7. As the cans are moved by the members 74: past the last ram 81 hereinbefore described, the cans are engaged by a guard 162'secured by a bolt 163 passing through a slot16 1 so that the guard may be moved toward and away from the member 74. Bolt 163 passes into aibracket 165 which is in turn adjustin Fig. .14. It will be evident that by this construction the guard 162 is rotatably adjustable both vertically and horizontally and at the same time a clear open space will be left around the table 70 so that any obstruction' which may fall upon the table will not catclt'iipon the guard or its support but will be readily discharged at the side of the tablef "At about the time that the can is engaged by the guard 162 one of the holders 149, hereinbefore described, will be lowered so as to engage with the can. Further movement of the can will bring it over a chuck 168 adapted to move vertically through an opening in the table 70. The chuck 168, as shown in'Fig. 26, has a portion 168 which fits the can body. This portion is fluted at 168 to cause it to adhere firmly to the can and is provided with a curved portion 168 for forming an outwardly extending flange on the can body. The curved portion 168 terminates in a shroud 168 which forms a position stop for the edge of the can body, thus regulating not only the flange formed but also the height of the com- The chuck 168 is carried upon a short shaft 170 which is journaled in a bracket 171. The shaft 170 has splined to it a bevel gear wheel 17 2 which engages with a second bevel gear wheel 173 on one end of the short shaft 17 1 also journaled in the bracket 171. At the opposite end of the shaft 174 is a bevel gear wheel 175 meshing with the bevel gear wheel 176 upon the shaft 177.

In order to move the shaft 170 it-is provided at its lower end with a collar 178 in which runs a band 179 provided with "tr unnions' 180 which are engaged by the forked end of a lever 181. This lever is formed in two parts pivoted together at 182 and is pivoted at 183 to the frame 53. The two parts of thelever 181 are moved relatively to each other by means of a bolt 18 1' and locking nuts 185. It will be evident that by moving' these locking nuts 185 the two parts of the lever may be moved relatively to each other and consequently the height of the chuck above the table can be regulated. In order to actuate the lever 181 it isprovided with an anti-friction roller 186',

This auti-friction in ounted thereof and. the said cam is engaged by a fork 1S8 mounted upon a rod 189 slidingly row the lever mounted in a bracket 199 carried on. the v ir-n-ne as best shown in Fi The rod lei? is iastened by means 01: a clamping m 1.1. H,

an 191 to hold the cam 1. in its operative position in ct the wheel 186 or at one side to throw the lever 151 out of operation.

Arranged, sirectl above the chuck 168 is a similar chuck 1" '2 carried on. a shaft 193. This shaft has keyed to its upper end a bevel gear wheel 1 94: meshing with the bevel 7 gear wheel 195 on the shaft 196 carried by the upper frame 60. vided on its end with a bevel gear wheel 197 meshing with the bevel gear wheel 198 on the shaft 177 hereinbefore referred to; It will thus be evident that the chucks and 192 willbe simultaneously rotated in the same direction. In order to move the '1 shaft 196 is prospindle 193 vertically the said spindle is engaged by means of a lever 199 pivoted at 200 to a block 201 adjustable in a bracket by means of a screw 263, as shown in detail in Fig. 17. In order to lock the screw 363 in any desired position it is provided with a hand wheel 264. the lower face of which is provided with notches adapted to with a spring detent 205. The pivot point of the lever 199 can thus be raised and lowered so as to secure the proper position of the chuck and at tile same time the detent lo a will locicthe wheel 261 and thus firmly hold said lever in its adjusted isition against accidental displacement; 'ine can body, after being caught between the chucks 168 and 19:2 is adapted to be operated upon by forming rolls so to form either internal or external flanges on the said'bedv, These rolls are carried a forming 207 which is pivoted at 268 to a bracli t KAI carried on the frame 60, as l c shown in. Fig. Each of the forming rolls 216 carried in a stem 211 slidingg'ly mounted a block 212. The end of the stem 211 is threaded and engaged with a threaded nut 213 by means of which the stem maybe moved longitudinally to advance the seaming roll 216 toward its cotiperating chuck or to remove it farther therefrom. block 212 i also slidingly mounted in the forming head 29? so as to adjust the roll 2ip vert-ically. This adjustment is obtained by means of a threaded rod 21%. passing through the said block 212 and a lug 215 The 30. This rod 1s engaged above the bracket 228 to allow for the passage of the fingers. In 95 I into the holders 149 so as to rest upon the 59. This rod 257 is provided at the inner 110 carried by the seaming head 207.

This bracket 239 carries a shaft 242 265 so that the limit oi the movement of 65 on which is mounted a pair of flexible the said pusher ar-m may be varied. This The upper end of the arm may also be vertically adjusted by means of a bolt 267 which secures it to the bar 259. The bar 259 is pivoted at one end to a bracket 209 hereinbei'ore described and at the other end bears upon a cam 269 carried upon the vertical shaft 125. The bar 259 is held against the cam 269 by. a spring 259. The can, after being supplied with its cap, is carried by the member 74; until it is brought over a chuck 272 shown in detail in Fig. 21. This chuck projects through. the table and is adapted to run loosely upon a short rod 273, ball bearings 27% being placed between the end of said rod and the chuck. The rod 273 is carried in a sleeve 275 and rests upon a coil spring 276 carried within the said sleeve. The sleeve is vertically adjustable and is clamped in position by means of screw 277 in a boss 278 on the frame 53. The upward movement of the rod 273 is also limited by means of a screw 279 passing through a slot 280 in the sleeve 275. The lower end'oi' the sleeve 275 bears upon one arm of a bell crank lever 281, the opposite arm of which is provided with an adjustable member 282 carrying an antifriction roll 28% bearing upon a cam 2Sl mounted uponthc vertical shaft The member 232 is pivoted to the bell-crank lever at 286 and is adjusted by means of a screw 287 passing: through a slot 288 as shown in Fig. .22. The movement. of the bell crank lover is limited in one direction by means of a screw 28%) and in the other by a screw 290 carried in a lug 291 on the b 'acket 292 supporting the bell c 'ank lever. By means of this construction additional pressure is placed upon the can body while the scam is being formed so as to insure a true double seam, as will be fully hereinafter set forth in connection with the complete operation of the machine.

Arranged above and in line with the chuck 272 is a chuck 295 carried upon a spindle 296 journalcd in the bracket 271 hereiubetore de scribed. The chuck 295 is provided with a flange 295 of just suliicient thickness to fill the depression in the cap or end piece. This chuck, as shown in Figs. 37 and 38, is also preferably provided on its lower lace with teeth 295 to prevent slippage between the chuck and cap. The chuck 295 as well as the other chucks carried on spindles, are preferably secured in position as will now be described.

- The spindle is o-fiset at 296 so as to lit-a central opening in the chuck. The reduced end of the spindle is split and is provided with a tapered opening in which its a taper plug 296 having a threaded inner end 296 which engages with a corresponding, thread in the spindle. The outer end of the plug is provided with a square tool opening; 296.

spindle 296 is provided 'cal play with a bevel gear Wheel 29? meshed with a bevel gear Whee1'298 on the shaft- 106 hereiubelore described. In order to move t spindle 296 vertically, a lever is p vided which is operated from a cam on horizontal cam shaft in the same manner the lever 199 hereiubefore described. 'n order that the spindle 296 may have while its chuck is seating on the can cap, the attachment of the operating; lever to the spindle is made as shown in .5. leveu299 is pivoted to a collar loose surrounding the shaft. This collar situatedbetween collars and i, secured to the spindle. The distance between the collars 293 .and 29a is somewhat greater than the thickiess of the collar It will be evident that as the spindle le scends the collar 293 will rest on the collar 285 until the chuck comes into contact with the top of the can and that the spindle will be free to move longitudinally until he colla 1' 285 comes into contact with the collar to exert pressure on the cap. ."kdjacent to the spindle 296 is a-spindle 300 which is rotated from the spindle 296 by means of an intermediate gear 301 as best shown in Fig. 2?. The bracket 271 also carries a stud which is arranged adjacent to the spin-d- 500. Pivoted on the studs 2'70 and are a pair or arms 303 and 304 which carry stems and blocks 211 and 212 respectively. like those above described in connection with the flang lug operation. The bar 808 held its -am by means of a spring 308. The stems 211 however carry aseaming ro 305 and a finishing roll 306 in place of the min llig rolls 21G hereinhetore referred to. The seaming roll 305 is provided with a 305 which cooperates With the flange 2.15 on the chuck 295. The roll 305 also [7T0- vided with an overhanging flange 305" which is beveled on its lower face as shown a t This beveled overhangring proper engagement of the so in the edge of the can cap. The arms 2 v. 304 are connected by a st ap ill)? by vfhirh is carried an arm 308 which bears upon a cam 309 on the vertical shaft Tie seaming roll 2505 and li hing roli therefore simultaneously actuated bvl 809. The spindh 3.00 carries a check 3 which is similar to the chi'iek 2953 herein )8- fore described except that the "hinge kill; is of greater depth than the depression in can cap so as to prevent the metal oi the cap 4 from being forced over the top elf the hangs,

thus causing the cap to adhere to the check.

The finishing roll 306 is provided with a cess 306 to receive the seam and an upwardly extending straight portion 30 3 as best shown in Fig. -9. The lower end of the can engaged by the cl'iuck the spindle 300 rests upon a chuck The shown in Flex
